. LUBBICATOR.

Specification of Letters Patent. Patented Nov. 23, 1920.

Application filed October 30, 1918. Serial No. 260,810.

I '0 all whom it may concern.

Be it known that I, LEVI S. GAMBILL a citizen of the United States, residin at elieiflin the county of Morgan and tate of Kentucky, have invented new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to new and useful improvements in lubricators which are actuated by steam pressure, and the principal object of the invention is to provide means for shutting off the supply of steam to the lubricator and draining the same to prevent the condensation water from freezing in the hibricator.

.lnother object oi the invention is to provide a device of this character which is simple and durable in construction, reliable and eflicient in operation and one which can be manutactu red and placed. upon the market at a minimum cost.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanyingdrawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a side View of a lubricator supplied with my invention.

Fig. 2 is a like view taken to Fig. 1.

Fig. 3 is a sectional view taken approximately on line 2-2 of Fig. 1.

In these views 1 is the receptacle for containing the oil or grease and 2 is the mem ber whirh is provided with the passages 2 :lor the oil and the passages 2 for the steam. The oil passages are controlled by the valve and the steam passages by the valve 6. The outer end of the member is at right angles 'ni'ovided with a chamber 2* through which the oil pipe 2* passes the inner end of said pipe communicating with the oil passages 2. The inner end of this chamber 2* is in communication with the goose-neck pipe 4 and the other end of the pipe l is connected with the steam dome 5 which has its lower end in communication with the steam passages 2. A small pipe 8' is carried by the inner end of the member and is in communication with the oil passages 2 in communi cation with the steam passages 2 and this pipe projects into the oil receptacle while a pipe 6 passes through the receptacle and has its end abutting a diaphragm 6" located in an extension of the receptacle. This provides an ordinary pulsating effect and forms no part of my invention.

In this manner the steam may be turned on so as to flow into the receptacle and thus create a pressure therein to cause the oil to flow therefrom.

When the plant is shut down at night, during freeing weather, the steam will condense in the receptacle and the resultant water will freeze and thus burst the receptacle.

In order to overcome this defect I place a shut off valve 7 in the goose neck pme 4 so that when the plant is shut down this valve is closed to prevent the steam from entering the dome and receptacle and then the receptacle is drained by removing the plug 8 in the bottom of the receptacle. This will remove the oil and water condensation from the receptacle and dome so that there is no danger of these parts being damaged by the contents freezing.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

I claim as my invention:

A lubricator of the class described comprising an oil receptacle, a member connected therewith and having oil and steam passages therein, valves controlling said passages, a steam chamber formed in the outer end of said member and an oil pipe passing through said chamber and in communication with the oil passages, an upright steam by-pass connected with said chamber and with the steam passages, a steam dome arranged in the bypass and a valve controlling the flow of steam through said by-pass.

In testimonv'whereof I affix my si nature.

LEVI SHERMAN eAMfiILL.
